PAPER-FOLDlNG-MACHINE ATTACHMENT FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 505,509, dated September 26, 1893.

Application filed November 25, 1892. Serial No. 453,046. (No model.)

To all whom it may concern.-

Be it known that I, TALBOTT C. DEXTER, of Fulton, in thecounty of Oswego, in the State of New York, have invented new and useful Improvements in Paper-Folding-Machine Attachments for Printing-Presses, of which the following, taken in connection with the accompanying drawings, is 'a full, clear, and exact description.

Manufacturers of paper folding machines have hitherto experienced considerable difficulty in connecting their machines to the so called flat bed printing presses owing to the different styles and proportions of presses of different manufacturers.

The object of this invention is to overcome said difiiculty by simple, inexpensive, convenient and efficient means; and to that end the lnvention consists in the novel constructlon and combination of parts hereinafter fully described and summed up in the claims.

In the annexed drawings Figure 1 is a side elevation of a paper-folding machine to a prlntlng press embodying my invention. Fig. 2 1s an enlarged front view of one of the supports of the tape-carrying devices. Fig.3 is a s1de View of the same. Fig. 4 is a detached slde View of the rider on which the shafts of the paper conveying devices are mounted. Fig. 5 is a horizontal transverse section on l ne w, as, in Fig. 3, and Fig. 6 is a top plan view of the end portion of the rider-supportmg base which is provided with sockets for the rider-retaining bolt.

Similar letters and figures of reference indicate corresponding parts.

B represents the feed-board of a printing press which may be of any style and construction at present in use; said feed-board belng firmly secured to the frame -F- of the press as indicated by dotted lines in Fig. 1 of the drawings.

O- denotes the paper folding machine which may also be of any well known construction. On the frame of this machine are mounted the rollers 1, 2, 3, 4., which, with the aid of other rollers hereinafter described, carry the tapes -5- which transfer the paper from the printing press to the folding machine.

The salient features of my present invention consist, first, in the transmission of the paper from the press to the folding machine by tape carrying mechanisms supported on the press independent of the folding machine, 5 5 thus obviating the loss of time and expenditure of considerable labor in fitting the folding machine to the printing-press; secondly, in a novel construction of the supports of the aforesaid tape-carrying mechanism which permits the latter to be readily disconnected from the press and also adjusted to its requisite position in relation to the delivery of the press so as to properly transfer the sheets of paper from the press to the folding ma- 6 chine, and in certain peculiarities of the details of the devices employed for the transmission of the paper from the press to the folding machine which I will now describe.

The aforesaid tape-carrying mechanisms may be supported on the printing press independently of the folding machine in various ways and I therefore do not wish to be confined strictly to the construction shown in the annexed drawings, which merely illustrates my preferred construction and which is as follows, to wit: To the feed-board B-- outside of the edges of the path of the paper issuing from the press, I secure pendent arms -AA on which the aforesaid tape-carry- 8o ing mechanisms are supported. Inasmuch as the feed board of different printing presses are disposed in different angles of inclination, Irender the arms -AA adjustable in their inclination in relation to the feedboard by pivoting said arms to the feed-ta ble, preferably by the intervention of segments or semi-circular brackets -D-D- firmly secured to the under side of the feed: board by screws or other suitable means and 0 having the arms -A-A pivoted to them so as to bring the peripheries of the brackets concentric to the pivots of the arms. Said brackets stand parallel to the line of travel of the paper and the arms A- are adapted 5 to be swung in planes parallel to the brackets and are clamped thereon adjustably to different angles of inclination by bolts lD- passingthrough the arms and through segmental slots in the brackets'or other suitable rco and well known means. The arms -AA are thus adapted to be swung toward or from the delivery cylinder I of the press and, in conjunction with other auxiliary devices hereinafter described, bring the paper receiving fingers f in proper position in relation to said cylinder.

In order to obviate the necessity of exercising great care and accuracy in placing the brackets with their arms AA in their positions in relation to the line of travel of the paper I support the upper tape-carrying mechanism of the paper transferring apparatus by means of the following adjustable brackets connected to the free ends of the arms AA. Each of said arms is loosely embraced by a sleeve a' which is adapted to be shifted longitudinally on the arm and thus raised or lowered as may be desired, and is retained in its adjusted position by set-screws nn connected to the sleeve and engaging the arm A. To the sleeve -a is attached the base bconsisting of a plate which is elongated at right angles to the arm A and at an angle to the plane'of the travel of the paper and is connected to the sleeve a adjustable laterally in relation to the arm A- by means of screws eepassing through a longitudinal slot -b' in the base b and entering screw-threaded eyes in cars on the sleeve. The top of the base bis provided with a longitudinal way b which is T- shaped in cross-section and on said way is mounted the rider -cwhich is adapted to slide thereon and is guided thereby. The top of the base b is also provided with one or more of sockets -c, and theirider has connected to it a spring-bolt d which enters one of the sockets and thereby retains the rider in its requisite position. Said rider is provided with sockets i and z"- in one of which is secured one end of the bar -lto which the paper-receiving fingers f are attached, and to the other of said sockets is attached one end of the bar 25 on which are mounted the brackets t to which are pivoted the rollers t" carrying the tapes which bear on top of the paper in transit from the press to the folder. Arms g depending from the rider have journaled to their free ends the roller-g which bears on the aforesaid tapes and holds the same in contact with the paper passing between them and the subjacent tapes, which latter run on a roller h journaled in bearings hon the riders c at opposite ends of the said roller. The aforesaid tapes pass around the usual rollers connected to the folding machine O. It will be observed that the paper-receiving fingers f and paper-carrying tapes, which transfer the paper from the press to the folder, are readily adjusted to the delivery of the press and to a proper plane between said delivery and folding machine, first by the adjustment of the armsA- as hereinbefore described, secondly, by raising or lowering the sleeves -a on the said arms, and thirdly by shifting the base -Z on the sleeve a.

The folding machine is readilydisconnected from the press when desired by simply removing the riders c-c from the bases b b, said riders carrying all the paper transferring devices as hereinbefore described. The sleeves aa with the bases bb remain on the arms AA and the latter are left in their adjusted position; hence when it is desired to connect the folding machine to the press, it is readily accomplished by simply slipping the riders c-conto the bases l)b where they are retained by the spring-bolts -dd entering the sockets in the top of the bases as hereinbefore de scribed.

In order to guard more effectually against the displacement of the arms 'AA from their requisite angle in relation to the feedboard B I attach to the segments D D adjustable stops or jam-nuts u against which the arms rest.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
